Sancho Panza and 30-minute walks

leave a comment »

I have taken a 30-minute walk each day for 5 days in a row. Now that the book is done (with Kindle edition being created by others and due to be available by 28 May), I have moved on to my next project, which is a 30-minute daily walk. The first four days were somewhat tiring, I have to say—I’m not very fit at all—but today was much better.

And I’ve returned to listening to Don Quixote, and right now (in Part 2) Sancho Panza and Don Quixote are guests of the (mean-spirited) Duke and Duchess, who had read Part 1 and thus are well-acquainted with Don Quixote and Sancho Panza, and are basically making fun of them while pretending to honor them.

Sancho got off a good line on a Baccalaureate, who (Sancho said) was educated at the university at Salamanca, and thus was to be trusted, “since he cannot lie, unless he wants to or it’s convenient.” :)

So I’m enjoying the walks and pleased that it is already not so tiring.

7-minute video workout

The above video is from an article in The Verge by Gregory Ferenstein, and I highly recommend you click the link and get more of the context of the exercise video. But I think it’s pretty cool. (Seems strenuous, though.)

Iyengar and the invention of Yoga

leave a comment »

Hatha yoga is quite old, dating back to the early 1930’s. Read this interesting article on how it was invented and by whom.

Overeating on carbs vs. Overeating on LCHF

leave a comment »

Interesting article at

Sam Feltham carried out an experiment a few months ago that caught a lot of attention. For three weeks he pigged out on low-carb LCHF foods, 5,800 calories a day.

According to simplistic calorie counting, Feltham should have gained 16 lbs (7.3 kg). But in reality, he only gained less than 3 lbs (1.3 kg).

Now Feltham has repeated his experiment with exactly the same amount of calories, but from carbohydrate-rich junk food. On the same amount of calories he gained more than five times as much weight: almost 16 lbs (7.1 kg)!

The difference in waist circumference was even more significant: 5,800 calories of LCHF food for three weeks reduced his waist measurement by 1 1/4 inches (3 cm). The same amount of junk food led to a 3 1/2 inch (9.25 cm) increase in his waist. And you can see the difference visually. . .

For those who are mildly obsessive in tracking things

leave a comment »

Take a look at this review of rTRACKER. I would buy it in a heartbeat if I had a smartphone—and if I had a smartphone, I think I would go with iPhone based on what I’ve been reading about security issues: Android phones, in being more open, are also more vulnerable. But even the iPhone is a little unsettling in how much info is collected.

Still, for me it’s not an issue: I’m mostly at home. But I do like rTRACKER.

A Low Carb Diet Meal Plan and Menu That Can Save Your Life

with one comment

A friend who knows I’m follow a low-carb, high-fat (LCHF) diet sent me this link, and the article at the link is quite good. We still avoid foods in the “Maybe Eat” section—certainly no grains, legumes, or tubers, and I’m cautious with carrots. Occasionally I’ll put some walnuts or pecans in a salad, but generally speaking, we don’t eat from that list. OTOH, we’re still involved in downsizing our weight. (Well, dark chocolate and wine really stayed in the diet, but limited to special occasions.)

I think I mentioned that when I told my doctor I was eating LCHF, he gave me a big thumbs up. He said that the diet is particularly good for diabetics. I had just had a blood test and he asked me to guess my HbA1c. I guessed 5.7%, it actually was 5.8%. The levels are:

  • Normal (no diabetes): Less than 5.7%
  • Pre-diabetes: 5.7% to 6.4%
  • Diabetes: 6.5% or higher

For most diabetics, the goal is to keep the level below 7%.

So I have something to work on…

Eight-year impact of a LCHF diet

leave a comment »

Very interesting report on what the blood panel looks like, year by year, for someone who has followed a LCHF diet for 8 years. From the link (where you can also find a chart showing the results from the blood panels):

The wild rumors about how dangerous LCHF is long term, don’t get validated in my blood work. After eight years on LCHF they are excellent, just as when I started. There simply aren’t any big changes during these years.

Many things are typical and the trends are also confirmed in studies on low-carb diets:

  • Low triglycerides (good)
  • Excellent HDL cholesterol levels
  • Nice ApoB/AI ratio
  • A low fasting blood sugar and a low HbA1c (good)
  • Low, but normal, insulin levels, measured as C-peptide (probably excellent)
  • A normal weight and a normal waist circumference
  • A low and good blood pressure

To summarize, all problems associated with the metabolic syndrome and type 2 diabetes usually improve on LCHF. Obesity, high blood pressure, high blood sugar, high insulin levels and dangerously disturbed cholesterol numbers (high triglycerides and low HDL).

My test results also show that the inflammatory level in the body – as measured CRP – is non-detectible on all test occasions.

With these results in mind the fantasy talk about long-term risks with LCHF doesn’t seem to be valid, at least not in my case. Perhaps you’ll have to put up with me for about 50 more years.

I’ve kept my weight at a normal weight level effortlessly and without any calorie counting during these years. I’ve gone up and down a few pounds within the normal range.

During my experiment with a strict LCHF diet and ketone measuring, I lost 12 lbs/5 kg. They came back when I returned to liberal LCHF, but disappeared again when I added 16:8.

My experience is that the latter is clearly the easier alternative. At least if you’re like me, and not that sensitive to carbohydrates. So I will continue with liberal LCHF with the addition of 16:8 on weekdays.

“16:8” is a new term for me. It means that each day you fast for 16 hours and eat only during an 8-hour period. In practical terms, it boils down to skipping breakfast. I have been doing that off and on, and I think I’ll try it more seriously. (Another number pair I just learned: 5:2, which refers to eating normally for five days and then two days eating only 1/4 the normal amount of calories—that is, on two days, a typical woman will eat 500 calories each day and a typical man 600.
